Influence the FeO Content on Slag Viscosity at his Spraying. Increase the Life of the Refractory Lining

Abstract

This article is concerned with one of the most important directions in energy and resource conservation in metallurgy—recycling of converter slag and the resulting enhancement of the refractory lining stability. Investigations using the Ribould and Urbain models where the dynamic viscosity of slag at temperatures from 1500 to 1650°C was determined on the basis of the chemical composition of slag from a Polish metallurgical combine are presented together with a comparative analysis with the results of the Fact Sage program. Computational results where the effect of FeO on slag viscosity for FeO content in the slag ranging from 5 to 30% are presented.
